| Jan 19, 2018 at 15:54 | comment | added | Radu | Worked really well, ty. Now that I know the magic behind it, I will try to experiment more, I will try to put it before the network target, since I'd like to shut down the networking at all (at least the wifi part of it). | |

Just replace your old disableusb.service with the new one – I've edited my post with the correct version now, so just copy that and put it in disableusb.service, then re-enable it.

I think I've spotted the issue, @Radu. Try copying the new unit in, then run systemctl reenable disableusb.service. I wrote base.target, should have written basic.target. Let me know if that fixes it.

Apologies, I didn't realise that systemd-analyse on its own didn't give you the unit chain. The output of systemd-analyze critical-chain should be what we need (this will show which units have loaded on boot), can you edit that in too?

| Jan 19, 2018 at 15:40 | comment | added | Radu | I did that also. Cool command btw, I used to time it with a timer on my phone (and it matches). | |

Hmm, definitely sounds like your unit never ran. Could you also edit in the output of systemd-analyze?

In that case, @Radu, could you please edit the output of journalctl -u disableusb.service into your question? Thanks.

For some reason it doesn't work. I made the file that looks like so: code[Unit] Description=Disable USB power Before=base.target After=local-fs.target sysinit.target DefaultDependencies=no [Service] Type=oneshot ExecStart=/sbin/usb_down [Install] WantedBy=base.target For some reason, that script doesn't run

| Jan 19, 2018 at 14:53 | comment | added | Radu | Btw, my script is actually just a line of code, "echo 0 | tee /sys/devices/platform/soc/20980000.usb/buspower >/dev/null" Can I just put that in ExecStart, or does it have to be a path to an actual script? | |
| Jan 19, 2018 at 14:42 | comment | added | Radu | Thank you very much. I will experiment with this, and if it works well, I will try to move it even earlier than that, until it doesn't work or it hangs on boot :) | |
